Thomas Paine

Common Sense and The Crisis Pamphlets were not published at the same time, but deal with similar topics. In Common Sense, Thomas Paine writes anonymously and is signed as "the Author", while The Crisis Pamphlet we read gives us Thomas Paine's identity, if not exactly by name, then by dates and events.

Is this because Thomas Paine feels those around him becoming bolder and he feels now is the time to call those around him to action? Or is he taking the chance that others will act once they realize it is a countryman (but not Englishman) of theirs that feels the same oppression?
